WALTER A. JACOBS, OF PORTLAND, OREGON.

AUTOMOBILE COMBINATION LOCK.

Application filed December 7, 1921. Serial No. 520,466.

To @ZZ whom t may concern.:

Be it known that I, WALTnR A. JACOBS, a citizen of the United States, residing in the city of Portland` county of Multnomah, and State of Oregon, have invented anew and useful Automobile Combination Look` of which the following is a specification.

This invention relates more particularly to an electrical combination on an automobile lock and having as its object a series of combinations for the purpose of engaging and disengaging the electric spa-rk.

I obtained these objects in the manner illustrated in the` accompanying drawings and set forth in the specifications following:

Figure 1. is the plan view of the lock; Figure 2. is a sectional View along the line A-A in Figure 7 with the post in the foreground; Figure 3. is a plan view of the stationary plate; Figure 4. is a plan view of the movable plate; Figure 5. is a plan view of the index plate; Figure 6. is an elevational view of the post, and Figure 7. is a plan view of the lock with the top cover removed.

Similar letters and numbers of reference refer to similar parts throughout the several views: No. 1 is the case; No. 2 the cover top; No. 3 the dial; No. 4 the index plate; No. 5 the knob; No. 6 the post; No. 7 index plate pin; No. 8 stationary plate; No. 9 plate pin;

To. 10 movable plate; No. 11 post spring; No. 12 post bearing; No. 13 breaker wheel; No. 14 connecting block; No. 15 inlet and outlet block; No. 16 connecting conductor;

No. 17 conductor and No. 18 conductor; No. 19 engaging slots; No. 20 plate fastening pin; No. 21 contact springs.

lt will be observed that this lock will securely lock any automobile, and that the car cannot be started except by means of working the combination, and that the car cannot be started when the lock is set, without working the combination, unless the wiring which affects the spark is all rearranged,

It will also be observed that the combination may be changed at any time, and that this combination, with other parts of the lock, constitutes a safe and efficient lock for an automobile.

The case may be made of any suitable material. The top shuts down with a gasket and fastens by means of bolts from bottom to top.

No. 6 is the post extending from the bottom to the top of the case. This post turns with knob No. 5 and the post turns in breakingthe circuit. At theftop there is fitted the index plate No. 4 by means of indexk plate pin No. 7; next fitted On top of the index plate is the knob No. 5 which screws on the topof the post. Plate No. 4 is milled down in the center to allow the knob and post to put down to unlock pin No. 9 in plate No. 10. This allows post braker wheel No. 13 to turn and break the circuit. The post is held in position by post bearing No. 12, and the spring No. 11. Above the spring No. 11 is a round plate No. 10 into which is fastened a pin No. 9, this plate is fastened to the post with'pin No. 20, above this plate is plate No. 8, containing 12 holes situated directly under the figures on dial No. 3. Plate No. 8 is riveted to the connecting block No. 14, thus in pushing down knob No. 5 and turning the arrow on plate No. 4 to any figure on dial No. 3, then releasing the knob, the pin in Jlate No. 19 would slip into a hole in plate o. 8 just under said figure, thus locking the knob into position. Post No. 6 between plate `No. 10 and between plate No. 4 is square.l No. 17 and No. 18 re late to the conductor, 16. No. 16 is the pin which makes and breaks connections of the circuit. Spring No. 21 is the tension contact for this connecting.

I claim:

1. In an automobile lock, a case containing a mechanism comprising, a post extended from the bottom to the top of said case, a spring at the lower end and surrounding said post, a pin extending through said post, a moveable plate having a hole in the center thereof, a stationary plate having' a hole in the center thereof adapted to fit on said post, and an index plate with a hole in the center thereof, a knob screwed to the top of said post, substantially as set forth.

2. In an automobile lock, a case comprising an operating mechanism within, posts extending from the bottom and through the top of said case, a knob screwed to the top of each of said posts, index plates about the posts below the knobs and above the cover of said case, pins in said posts to engage with said index plates, stationary plates mounted within the case about said posts, movable plates mounted on said posts adjacent to said stationary plates, a pin projecting troni each of said movable plates to engage with each of said stationary plates, a spring surrounding the lower end of each of said posts, substantially as setforth.

3. In an automobile lock, a oase containing a mechanism comprising, posts extending from the bottom to the top of said ease, springs at the lower ends and surrounding said posts, movable plates arranged cireurnferentially about said posts, a pin eX- tending through each of said posts, stationary plates having holes in the center and a series of holes near the outer edge thereof, a Wheel arranged cirouinerentially about each of said posts with a. metallic pin therein, stationary plates above and below said Wheel with metallic contacts, substantially as set forth.

4L. n an automobile lock, a post, a pin eX- tending through the top end of said post,

a knob screwed to the top end `ot said post, an index plate arranged oiroumferentially about the top end or" said post and engaged by said pin, a moveable plate arranged eirouniferentially about said post, a pin ex` tending through said post near the lower end thereof. a stationar;7 plate arranged oircuiniierentially about said post having a series of holes near the outer edge thereof, a Wheel, a spring surrounding the lower end of said post, a Case containing the ine- -hanisrn above substantially as described.

n testimony whereof, I have hereunto set my hand in the presence of two suhscribing Witnesses.
